Abstract: Man hat bereits die Elektrolyse wässriger Alkalichlorid-Lösungen unter Druck durchgeführt. Erfindungsgemäss wird nun bei einer solchen Elektrolyse ein Druck von mindestens 8 bar im Anodenraum (79) sowie ein spezielles Verfahren zur Aufarbeitung der Produkte des Anodenraums (79) angewandt. Das aus dem Anodenraum (79) strömende Gemisch von Gas und Anolyt wird zunächst mechanisch getrennt und dann der Anolyt in eine Stripkolonne (56) entspannt. Dabei findet eine Entchlorung und eine Abkühlung des Anolyten statt. Der Anolyt soll in das Entspannungsgefäss (56) mit einer Temperatur eintreten, die über der Siedetemperatur des Anolyten bei Atmosphärendruck liegt. Der Entspannungsdruck soll zwischen 2 bar und Atmosphärendruck liegen. Mit diesen Massnahmen lässt sich erreichen, dass der Anolyt in der Stripkolonne (56) zum Sieden kommt. Schliesslich wird das bei der Entspannung freigewordene Chlor vom Anolyten abgetrennt. Alternativ kann man in der Stripkolonne (56) den Anolyten im Gegenstrom mit Wasserdampf behandeln, bis er siedet; der durch die Entspannung und Wasserdampfbehandlung von Chlor befreite Anolyt wird sodann von der entstandenen Gasphase abgetrennt.

Abstract: A multilayer filter material is proposed which contains at least one layer (1, 1', 1'', 2, 2', 2'') of an open-pore foam material. In order to achieve a sufficiently high air permeability in such a material but at the same time to prevent continuous large pores or cavities occurring, it is proposed to cover one layer (1, 1', 1'') at least on one side with a further layer (2, 2', 2''), firmly attached to the first, of an open-pore foam material. It is particularly advantageous if a comparatively thin foam layer (2, 2', 2'') of small pore size is joined to a further foam layer (1, 1', 1'') having a greater thickness and larger pores than the first layer. <IMAGE>

Abstract: A wire wrapping tool comprises a head 10 which is formed integrally with a shaft 11. The head 10 includes a frusto-conical portion 16 which has a chordally extending portion cut away to define a cutting edge 22. A blade portion 18 is formed on the head, the blade having a slot 44 through which a wire can pass. The head also has an axially extending bore 34 into which a wire wrapping post can be inserted. In use the shaft 11 is attached to a pistol gun to rotate the head. Wire from which the insulation is to be stripped is passed over the edge 22, through the slot 44 and around a wrapping post. As the wire passes over the edge 22 a longitudinal slit is formed in the insulation which is then stripped away from the conductive core as the wire passes through the slot 44.

Abstract: A vibratory device (10), such as a dental scaler, in which an air-driven rotor (60) is driven about a shaft (42) to impart vibrations thereto and drive a work tool (24) or other object attached to the shaft (42). A portion (51) of the shaft (42) beneath the rotor (60) has an enlarged diameter such that axial movement of the rotor (60) caused by shaft wear is continuously corrected during rotation. Chamfered end edges (65) of the rotor (60) minimize pressure differentials at the end of the rotor edges (63) and consequently assist in centralization of the rotor (60) about the fluid outlet (70) on the shaft (42). The fluid outlet comprises outlet ports (70) in the shaft wall beneath the area of rotation of the rotor (60) and having chamfered outside end edges to minimize power losses from turbulence. Additionally, a support (30) is provided along the shaft (42) at a desired vibratory node and has sufficient non- resilience to bias the shaft (42) into the desired mode of vibration.
